The E-to-E repair is applicable to lesions of any etiology and it is effective not only when MR is due to
leaflet prolapse, but also with other types of valve
dysfunction. Due to its intrinsic simplicity, the E-to-E
repair could be the technique of choice when exposure
is difficult or when the repair is carried out through a
port access. Eventually, the concept introduced by this
type of repair can open the perspective of percutaneous
correction of MR. Longer follow-up period is needed
to confirm long term expectations with this promising
alternative technique of valve repair.
